The output supplies, thus enabling the input stage to be operated propagation delay for rising and falling signals is similar, and from 5 V dual supplies or a 5 V single supply while maintaining a tracks over temperature and voltage. These characteristics make CMOS-/TTL-compatible output. the AD8564 a good choice for high speed timing and data communications circuits. For a similar single comparator with Fast 7 ns propagation delay makes the AD8564 a good choice latch function, refer to the AD8561 data sheet. for timing circuits and line receivers. Independent analog and digital supplies provide excellent protection from supply pin The AD8564 is specified over the industrial temperature range interaction. The AD8564 is pin compatible with the MAX901 (40C to +125C). The quad AD8564 is available in the 16-lead and has lower supply currents. TSSOP, 16-lead narrow body SOIC, and 16-lead plastic DIP packages. Rev. B Information furnished by Analog Devices is believed to be accurate and reliable.
